Interesting I have had 3 surgeries (two abdomen and one transplant) in the last year in the UK and they used paper based systems and verbal instructions for the two planed ones.

The NHS still runs on paper :-) still cant do my regular bloods at my local ahead of my regular check up at another specialist hospital.

We'd love to explore the UK but have no clue what's the best way in. Any suggestion?

Perhaps not obvious, but you can expect to need to do localization: https://news.ycombinator.com/item?id=16333599

That might be a place to start, with translation and localization of instructions.

Not sure I can ask at my next nephrology appointment I would suspect approaching individual NHS trusts.
